php发送邮箱简单教程

Posted 2022-12-10 行走江湖的码农

在这里使用163邮箱做演示，也使用其他的比如126 ，qq的

<?php
error_reporting(0);
    /**
     * 注：本邮件类都是经过我测试成功了的，如果大家发送邮件的时候遇到了失败的问题，请从以下几点排查：
     * 1. 用户名和密码是否正确；
     * 2. 检查邮箱设置是否启用了smtp服务；
     * 3. 是否是php环境的问题导致；
     * 4. 将26行的$smtp->debug = false改为true，可以显示错误信息，然后可以复制报错信息到网上搜一下错误的原因；
     * 5. 如果还是不能解决，可以访问：http://www.daixiaorui.com/read/16.html#viewpl 
     *    下面的评论中，可能有你要找的答案。
